Improved door and window fastener



Nrrnn STATES HENRY VILKINSON, OF NEWBURG, NEW YORK.

IMPROVED DOOR AND WINDOW FASTENER.

To all whom it may concern 'transverse vertical section of the same.Figs.

3 and 4 are detached views of the double set of roller-bits foroperating the bolts. Fig. 5 is a modification of the same.

Similar letters of reference in all the iigures indicate correspondingparts.

This invention consists in two double-armed lever-bits applied to acommon revolving barrel, and operating in combination with springf1ames, which carry the bolts and move in opposite directions in such amanner that by turning the barrel in either direction the bolts aredrawn in simultaneously, and the door, window, or other device isunfastened, and by releasing the barrel the springs acting on the framesforce the bolts out to the proper position for fastening the door orwindow.

The invention consists also in a sliding or oscillating latch, incombination with the reciprocating spring frames and bolts, in such amanner that by the action of said latch the frames are locked and thedoor or window can be securely fastened.

A represents a case made of sheet metal or other suitable material.which is mortised into the closing-edge of a door or window, and whichmay be provided with a anged faceplate, a, in the usual manner ofmortised locks. The side plates, b b, of the caseA form the bearings forthe revolving barrel c, which is provided with a square hole to admitthe stem of the handle B, by means of which the barrel can be rotated ineither direction. The barrel c carries twobits, d d', which are attachedto the same on opposite sides, so that the same in turning the barrelact in opposite directions. Said bits are situated in diiferent places,and the bit d acts on a frame, e, while the bit d acts on a frame, c',and said frames are arranged within the case A, one above the other,

as clearly shown in Fig. 2 of the drawings. A spring, f, forces theframe e up, and a similar spring, j", forces the frame c down. The bitsd d are double-armed, as clearly shown in Figs. l and 4, so that byturning the barrel in either direction the frame e is forced down andthe frame c is forced up, and bolts g g', which are secured in the frames e c, are caused to make a corresponding motion. The bolt g extends upthrough a mortise in the door or window, and when the frame e is in itshighest position and the door or window is closed the head of said boltcatches in a socket, h, in the door or window frame O, and the bolt gextends down through a corresponding mortise in the door or window, andwhen theframe eis at its lowest position the head of the bolt catches ina suitable socket, h', in the sill of the door or in the lower bar ofthe windowframe, provided said door or window is closed. By turning thehandle B in either direction, both bolts g g are drawn insimultaneously, and the door window can be opened. In closing the dooror window the heads ofthe bolts slide up the inclined edges of thesockets h h and catch in them without the necessity of touching thehandle. The friction between the ends ot' the bits d d and the slidingframes c c', and also the friction between the ends of the bolts and theedges of the sockets, is reduced by friction-rollers inserted into theends 0f said bits and bolts.

If it is desired to lock the door or window so that it cannot be openedwithout the proper key, a latch, D, is made to catch in a recess, i,formed in the upper edge of the sliding frame e close below the loweredge of the frame c. This latch may either be suspended from a revolvingbarrel,j, as shown in Fig. l ofthe drawings, or it may be made to slidein and out, as shown in Fig. 5, and in the latter case a common bolt maybe connected with it so that the latch and bolt move simultaneously, andby the bolt the door or window is locked in the ordinary manner.

The latch is operated by a suitable key, and if the bolts g g arefastened by means ot said latch the door or window cannot be openeduntil by inserting said key the latch has been turned back.

This fastening is applicable to doors of any description, and to suchwindows which are hung on hinges and known by the term of Frenchwindows. It is easily attached, it leaves the surfaces ofthe door orsash in good condition, and all its parts are so constructed that theyare not liable to get out of order.

What l claim as new, and desire to secure by Letters Patent, is- Thecombination of the two doubled-headed armed lever-bits d df, therevolving barrel c, and the sliding,` plates e c with the bolts g g andthe latch D, whereby a door can be secured at top and bottom, andthebolts be withdrawn by a single turn of the knob, either right or left,substantially in the manner described and represented.
